摘要： A system for publishing data on shared broadcast channels using spread-spectrum techniques, which may comprise a spread-spectrum encoder capable of receiving data and placing it in a spread-spectrum signal format and a transmitter operating on a shared communication channel or frequency band, such as might be allocated to terrestrial point-to-point or broadcast communications. The shared communication channel may comprise a cellular system, in which data may be transmitted using spread-spectrum techniques using the transmitters and repeaters of the cellular system simultaneously with voice and other transmissions associated with the cellular system. A subscriber station may be capable of receiving using a plurality of different communication channels or frequency bands, such as a first receiver capable of cellular reception and a second receiver capable of satellite reception, at least one of which uses spread-spectrum techniques. The subscriber station may also comprise a transmitter using at least one communication channel or frequency band, so that the subscriber station may receive data or other transmissions using one channel and may request further data or other transmissions using a second channel.

摘要： Forward link communication is achieved utilizing a conventional television broadcast station, either utilizing an entire presently unused TV channel or in a shared TV mode, with the return link communication being achieved using narrow band communication techniques for relatively low data rate communication through conventional television receiver aerials to a central receiver near the television station transmitter. The carrier reference of a local AM radio station is used as a synchronizing reference for the data streams and to allow the very close sepraration of each band in the return communication link to allow a large number of remote receivers to simultaneously communicate in the reverse link. Alternatively, the TV Chroma subcarrier serves this purpose.

摘要： In a TV answer back system where many receiver stations communicate with a TV transmitter station by means of rf pulses generated by rf oscillators at the receiver station, the requirement for keeping all oscillators on frequency is achieved without crystal temperature control by automatically controlling the rf oscillator frequency using synchronization signals carried in the video signal received from the TV studio. By this invention it has been possible to control the frequency of multiple megahertz oscillator as accurately as desired from relatively low frequency synchronizing signals such as the vertical and horizontal video sync pulses. Thus an oscillations counter is gated for a very accurate time period by the sync pulses, and the oscillation count is compared with a datum count representing the desired oscillation frequency. The requirement to prevent receiver stations from answering with rf pulses in response to queries contained in home video recordings of previously broadcast signals is achieved by encoding broadcast time on all query containing TV transmissions, and by comparing at receiver stations broadcast time information from received signal with time from a local battery backed clock contained at each receiver station, thus discrimination of video recordings is possible by comparing received video broadcast time with local time.

摘要： Provided are a method for adjusting a broadcast receiver queue, an apparatus, a storage medium, and an electronic device. The method may include: acquiring a historical parameter of a broadcast receiver; determining whether the historical parameter meets a first predefined condition; when the historical parameter of a first target broadcast receiver in a first broadcast receiver queue meets the first predefined condition, generating a second broadcast receiver queue; and moving the first target broadcast receiver to the second broadcast receiver queue, such that broadcast receivers other than the first target broadcast receiver in the first broadcast receiver queue and the first broadcast receiver in the second broadcast receiver queue may process the broadcast messages in parallel.
